We used a CW-YAG endolaser to photocoagulate the fundus of the rabbit and monkey. We varied the power settings, exposure durations, and probe-retina distances to establish the parameters for threshold and bursting (choroidal hemorrhage) lesions. We found that the amount of energy needed to create a retinal lesion increased proportionally with the distance between the probe and the retina. To produce a choroidal hemorrhage at a given distance required at least four times the power required for a threshold coagulative lesion at the same distance. We also found that we could achieve a strong choroidal reaction without hemorrhage by using the coagulative threshold parameters of power and distance with an increased exposure time. Photocoagulation of the retina using the CW-YAG depended on the presence of melanin.
我们使用连续波钇铝石榴石（CW-YAG）眼内激光对兔和猴的眼底进行光凝。我们改变功率设置、曝光持续时间和探头与视网膜的距离，以确定阈值和爆发性（脉络膜出血）病变的参数。我们发现，产生视网膜病变所需的能量与探头和视网膜之间的距离成正比增加。在给定距离产生脉络膜出血所需的功率至少是同一距离阈值凝固性病变所需功率的四倍。我们还发现，通过使用功率和距离的凝固阈值参数并增加曝光时间，可以在不出血的情况下实现强烈的脉络膜反应。使用CW-YAG对视网膜进行光凝取决于黑色素的存在。
